Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525642, here are decompositions:

23 + 33525619 = 33525642
71 + 33525571 = 33525642
89 + 33525553 = 33525642
109 + 33525533 = 33525642
113 + 33525529 = 33525642
151 + 33525491 = 33525642
193 + 33525449 = 33525642
263 + 33525379 = 33525642

Showing the first eight; more decompositions exist.
